Overview
The LTC2374CUH-16#PBF is a high-performance, 16-bit successive approximation register (SAR) analog-to-digital converter (ADC) produced by Analog Devices Inc. This device is part of the LTC2374 series and is known for its low noise, high speed, and highly configurable design. It operates from a single 5V supply and features an 8-channel input multiplexer, supporting fully differential, pseudo-differential unipolar, and pseudo-differential bipolar analog input ranges. The ADC achieves high accuracy with ±1LSB INL (maximum) and no missing codes at 16 bits, along with a high signal-to-noise ratio (SNR) of 96dB for fully differential inputs and 93dB for pseudo-differential inputs.
